The Wolfs are excellent primers. Stay away from the small rifle ones though as previously posted, they are for low pressure cartridges. For .223 I use the small rifle magnum. The only difference between the two is cup thickness according to a fellow named Bob Jensen in AZ who was the original importer of the Russian KVB primers (now under the Wolf name) and has done extensive testing of the new Wolf primers. He was involved with the US Palma team back then. I use the large rifle size for 6XC and .308.

Quoted:
There are 3 different primers for each. I know that Wolf imported and sold the true 5.56 primer, but not real sure about the Nato type primer for the Large rifle.

Here you will see the Three Small Rifle primers


We stock the KVB-223 and the KVB-556M, The 223 has a copper cup, and is for use in Bolt gun applications, the 556M Has a harder cup to aid in the prevention of slam firing, similar to what you have in CCI's Standard and Military primers. With Wolf's Standard being softer
There is a slight temperature difference between the 223 and 556 but nothing like the difference between the 223 and the 223M. The 223M is a true full blown Magnum primer.

I have shot the Standard Small Rifle in the 6PPC Cartridge /Stolle Panda Action with no failures, However a few shooters did pierce them. I really think it is a difference in the size of firing pin hole in the bolt face, mine is sleeved. Our Savage test rifle did fine, But our rem 700 PSS pierced them.

We tried the 556 primers and experience no failures in any of our rifles.

Anytime you make a component change you need to reduce and work up your loads to be on the safe side


Now to your Question about the Large Rifle, Same scenario



Here we do not stock the Nato listed primer, it was not available at the time. And in the case of the Large Rifle the Standard KVB-7 is a standard cup not softer copper like in the Small Rifle line. Differences will be that the 762 has a harder cup and is a little hotter than the Standard primer, but not a significant difference like there is between the Standard and Magnum primer as far as temperature.

Using a Wolf Standard Large Rifle Primer in a Semi Auto will be like using a Standard  Large Rifle Remington Primer

And Again Anytime you make a component change you need to reduce and work up your loads to be on the safe side



Hope this helps someone, I am going to bed now

we need to tack a thread about wolf primers!

Quoted:
We have sold over 100 million of the Wolf primers.  As with any primer you will have some people who say they hate the primer and some who absolutely love them.  We have had very, very few complaints regardin the Wolf primers.  The #1 complaint was the AR's piercing the primers.  This is the sole reason Wolf began importing the "223" primer.  It is specifically designed for AR style rifles.  If you will be using primers in an AR make sure you purchase either the 223 or the Small Rifle Mag.  Some people swear by one over the other but with my personal experience I prefer the 223 primer.
